Merge tag 'spi-fix-v4.5-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi 

Pull spi fixes from Mark Brown:
 "A small clutch of driver specific fixes.

  The OMAP one is a bit worrying since it seems to be triggered by some
  changes in the runtime PM core code and I suspect there's other
  drivers across that are going to be using the same pattern outside of
  OMAP but nothing seems to be coming up in the testing people are
  doing"

* tag 'spi-fix-v4.5-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi:
  spi: omap2-mcspi: Fix PM regression with deferred probe for pm_runtime_reinit
